SASH-HOLDER.

SPECIFICATION forming part of Letters Patent No. 310,983, dated January20, 1885.

Application filed July 24, 1884. (No model.)

To aZZ whom it may concern:

Be it known that I, FREDERICK BURMEIS- TER, of Cleveland, in the countyof Guyahoga and State of Ohio, have invented certain new and usefulImprovements in Sash-Holders, of

which the following is a specification.

This invention relates to sash-holders and it consists in the peculiarconstruction and op eration of the parts constituting my device, as

hereinafter described and claimed.

In'the accompanying drawings, Figure 1 is a perspective view of my newsash-holder. Fig. 2 is an under side view. Fig. 3 is a detached wiew ofthe locking-bolt, showing the [5 swivel-jointed head. Fig. 4 is alongitudinal section of the same. a

This device consists of three cast metal pieces only,of the followingpeculiar construction and combination.

A represents a baseplate having holes for securing it to a window-sash,and is provided with a housing, a, in which a turn-bolt is located. Oneend of said housing is made open, while the other end is closed by aninclined wall, through which there is a hole, a.

B is a bolt having a spiral shoulder, 12, terminating in a reducedp0rtion, b, forming a journal which plays in the aforesaid hole a. Saidbolt has a lever, G, for turning it. The

3o bolt also has a swivel-j ointed head, D,which is permanentlyattached.

It can revolve onthe bolt, but cannot be taken off. It is constructed inthe following manner: The bolt is first cast with a wrist-pin, d, havinga bead around it. The said wrist-pin is then coated with coresand, andthe head D is cast around it. This prevents the head adhering to thepin, and allows the sand to be worked out, leaving the head loose, andmay revolve thereon. The spiral shoulder 12 rotates against the inclinedinside surface of the wall when the bolt is turned one way for throwingit outward, and the lever rides against the outside inclined surface ofsaid wall when the bolt is turned back again. This draws the bolt backin again.

The purpose of this device is to hold the sash to which it is attachedby the pressure of the head D against the adjacent windowframe.

Having described my invention, I claim The combination. with the housingA, having inclined wall provided with hole a, of the bolt B, havingspiral incline b, and reduced portion 1), terminating with lever O, andprovided with the swivel-jointed head D, cast thereon, constructed,combined, and operating substantially as described, and for the purposeset forth.

FREDERICK BURMEISTER.
